What are the common misconceptions in sow raising? What farmers need to know

Pig farming is the most common livestock project in our country. When raising pigs, if you want to ensure continuous and efficient farming, then the work of raising sows is very important. Only by raising sows well and improving their reproductive performance can you ensure the healthy and stable development of the pig herd. However, many pig farms have a great many misconceptions when raising sows. So what exactly are they? Below, the editor will briefly introduce the common misconceptions in sow raising. Let's take a look!

1. Abusing mold removers

Feed is extremely important to the growth of sows, so we need to pay close attention to the quality of the feed. If moldy feed is fed, it will have a very large impact on the reproductive performance of sows. Many unscrupulous companies therefore vigorously publicize the harms of moldy feed in order to promote the mold removers they produce. This leads pig farmers to use mold removers in large quantities for long periods. Whether mold removers can effectively break down mycotoxins still needs further verification, so abusing mold removers is highly inadvisable.

2. Abusing estrus-inducing hormones

Although properly injecting estrus-inducing hormones into sows does have a fairly obvious effect, most sows will only come into estrus without ovulating, which seriously affects the success rate of mating. Moreover, although some sows appear on the surface to have mated successfully, the rate of empty pregnancy is also very high. This leads to a decline in the farrowing rate of sows, and in severe cases, false pregnancy occurs with no embryo implantation. If estrus-inducing hormones are used for a long time, it is very likely to cause a decline or even atrophy of the sows' ovarian function, resulting in reproductive disorders such as delayed estrus and absence of estrus.

3. Abusing oxytocin

At present, many pig farms use oxytocin, mainly to shorten the farrowing process of sows and advance the expulsion time of the afterbirth. However, if oxytocin is used in large amounts for a long time, the harm to sows will also be very great. For example, it may cause the umbilical cord of piglets to break prematurely, leading to the death of piglets in the birth canal. It may also cause the amniotic fluid to rupture, causing dystocia in sows. In addition, sows secrete less colostrum, and the survival rate of piglets is low. At the same time, it will also have a great impact on the endocrine system of sows, so oxytocin must be used reasonably. In addition to this, attention should also be paid to the use of uterotonics.

4. Endometritis

Endometritis is a major factor causing reproductive disorders in sows. It is also the main cause of sows returning to estrus and giving birth to weak piglets. If a sow is constipated or the intrauterine environment is artificially damaged, it will lead to an increase in weak fetuses, thereby causing endometritis. It is generally mainly manifested as follows: when a sow is in estrus and giving birth, the cervix dilates. Pus and blood or yellow liquid easily appear and are continuously discharged, causing the sow not to come into estrus or to fail to conceive. At this time, we should pay attention to the reasonable use of progesterone to avoid premature birth and stillbirth.

The above is a brief introduction to the common misconceptions in sow raising. That's all for today's introduction. This article is for reference only, and we hope it can be of some help to everyone!
